摘要： The invention relates to charged filtration membranes and their use for separation of a protein from solvent, low molecular weight solutes or a mixture of proteins. Modification of the membranes to generate charge includes modification of membrane pores to alter charge within a pore and alter the size of a pore. Consequently, the protein is separated from other solutes in a mixture based on size as well as net protein charge and membrane charge.

摘要： The present invention relates to the production of a novel membrane having a larger number of small sized pores therein such that the product rate in a reverse osmosis separation using said membrane is substantially increased for a particular separation factor. The invention is predicated upon the concept that the performance of a membrane in reverse osmosis separation is primarily dependent upon two interrelated factors, namely the structure of the polymer solution from which the film is cast and the evaporation rate during the period of evaporation of the organic solvent from the cast film. The present invention thus provides processes in which the solvent structure of the solution and the evaporation rate of the solution from the cast film is adjusted towards an optimum for producing a large number of small pores in the surface layer of the membrane to increase substantially the product rate at a given separation factor.
摘要翻译：本发明涉及生产具有更多数量的小孔的新型膜，使得使用所述膜的反渗透分离中的产物速率对于特定的分离因子而言显着增加。本发明基于以下概念：膜在反渗透分离中的性能主要取决于两个相关因素，即膜的浇铸聚合物溶液的结构和蒸发有机物期间的蒸发速率溶剂从流延薄膜。因此，本发明提供了将溶液的溶剂结构和来自流延膜的溶液的蒸发速率调节到适于在膜的表面层中产生大量小孔的最佳方法以大大增加产物的方法速率在给定的分离因子。
